These scrapers are made as inexpensively as possible and do not provide a good hand grip for the user while scraping, and also they fail to provide any attachment to a pole for overhead use.

Particularly in retail stores, signs, paint, tape, etc., must be removed and changed at an elevation as in a store window or on a wall, and therefore a ladder is necessary or merchandise must be removed, and then afterwards replaced, from a display window in order for the user to accomplish the purpose of scraping away old signs, etc., and a great deal of time is consumed by fetching and returning the ladder, removing and replacing the merchandise, etc. In addition, the ladder does not present a firm support for the person doing the scraping.

SUMMARY OF THE INVENTION A blade holder housing is provided to accept a conventional razor blade scraper device in which the blade is extensible for use and retractable for safety. The housing is made so that a thumb or finger operation of retracting and extending the blade is easily carried out with the scraper lodged frictionally in the housing in position for presenting the blade for use or retracting it for safe storage.

The razor blade scraper housing is permanently mounted on a plate which forms the terminal of a hand grip and pole adapter, which is preferably tapered and slit for ease of securement and for solidly holding a pole in position. This adaptor hand grip is located at an angle with respect to the general plane of the razor blade scraper and its housing of approximately 30 or thereabouts and this angle has been found to provide an excellent manual grip or handle without the pole; with the pole the scraper may be turned to present the blade substantially horizontal or turned over to present it at an angle of a few degrees with respect to the surface being scraper, thereby making the scraper more handy and efficient in use.

PREFERRED EMBODIMENT OF THE INVENTION There is provided a generally rectangular housing 10. This housing includes side walls l2, 12, a rear end wall 14, and has a front open area from wall 12 to wall 12 as at 16.

The housing also has a bottom 18, this bottom being substantially continuous and if desired it may be slit forming leaf springs 19 by which to hold a spare blade.

Referring now to FIG. 6 there is here shown a commercial razor blade scraper. It has a generally rectangular housing 20 with a slot 22 in its upper surface, slot 22 having end notches 24, 26, these notches being spaced for locking a thumb or finger slider 28 in either the exposed condition of the blade 30, see FIG. 6, or housed condition thereof within the edge 32 for safety. In this position the thumb piece 28 will be locked in the notches 26, see FIG. 2.

The top surface of housing 10 is provided with a relatively large opening 34 which extends from a line or edge 36 rearwardly to the rear wall 14 for accommodating the thumb piece 28 and the slots 24, 26 so that they are available for access.

The top surface of housing 10 also has a forward opening 38 to facilitate the application of the scraper shown in FIG. 6, to assemble it inside the housing 10. To this end, the rear end of the scraper in FIG. 6 as at 40 is inserted into the open end 16 of housing 10 and when the finger piece 28 is in the opening 38 it is depressed and slid under bridge 42 of the top wall of the housing popping up when it clears the edge 36 of opening 34. As the scraper is pushed to the right, i.e., to the rear, see FIG. 3, it becomes increasingly wedged in position appearing as in FIG. 2 when finally set so that notches 24 can be utilized and are not under the bridge 42. In this condition of the device the scraper is used exactly as it was previously for extending the blade 30 and retracting it by means of the thumb piece 28. In order to extract the well seated scraper from the housing 10 it is only necessary to insert a coin in an access opening 46, see FIG. ,2, and twist the coin to eject the entire scraper.

The lower wall or floor 18 of the housing 10 is permanently connected to a plate 48 which forms a pennanent integral part of a tapering hand grip and pole adapter 50. This adapter is preferably slit as at 52 for accommodating a pole shown in broken lines at 54, FIG. 1, and it may also be provided with a hangup clip if desired. The plate 48 is located with respect to the adapter 50 at about 30 angle although this angle is not critical and it will be seen that it can be used as a very good grip without the use of pole 54. If a pole is used then the device can be used with the scraping blade substantially horizontal or it can be flipped over in which case the blade will now be at a very slight angle to a vertical wall to be scraped.

I claim: I

l. A blade scraper comprising a flat, co-planar housing, a front opening therein, a scraper, means for slidably receiving and releasably holding the scraper in the housing through said opening, a blade in the scraper, means for retracting said blade within said scraper and said housing and for projecting the same to an operative position through said opening,

and a handle for manual manipulation of the scraper,

the handle being mounted on the housing and located at an angle with respect thereto, said handle extending generally away from said front opening,
